Dominant vegetations were deciduous trees (oak trees) such as Quercus mongolica, Q. vuriubilis, Q. acutissima, Q. aliena, and Q. serrata in Tohamsan and Danseoksan areas while dominant species was Pinus thunbergii in the Daebon area and P. densiflora in the Gumisan, Namsan, Sogeumkang, Hwarang and Seoak areas. Pte-Q was It was higher than in mountainous inland areas, which was desirable succession. Key words : Flora, Gyeongju National Park Introduction The first research into the plants in Korea was the research conducted by the Russian Scientist, Schlippenbach, B. A. (1854), who collected 50 or so floral species in the East Sea and sent them to the western nations. Then, fathers Faurie, R. P. U. and Taquet, E. J. collected samples and sent them to the scientists in Europe, which was published in the academic circle. Palibin, J. W. (1898~1901) organized their research findings and published Conspectus Florae Koreae. After that, a Japanese scientist, Nakai (190, 1911) compiled and published Flora koreana (I, II). After the liberation of Korea from the Imperial Japan, Chuong (1956, 1957) published the picture book of Korean plants, which served as a breakthrough to the development of the botany of Korean peninsula, revitalizing botanical research by the Koreans. However, the western materialism that swept Korea with the liberation accelerated industrialization, which shifted the focus of national policies to industrialization and development. As a result, industrial complexes, residential areas and furthermore, entertainment areas made inroads into national land. With the destruction of national land, most of living creatures were placed in life-threatening danger. Although some areas are designated and protected as national parks, these areas barely escape from serious devastation. Unfortunately, the government cannot *To whom correspondence should be addressed. Tel: smlee0998@hanmail.net even come up with countermeasures. Most of species (about 70%) are inhabited in national parks and natural conservational areas, but with lack of scientific and academic research into these areas. It is realistically difficult to set up protection and preservation policies of the species. Though intensive research is recently conducted in some of national parks and conservation areas, it is extremely short-lived and limited. Thus, this research was intended to provide basic data for further research, preservation and maintenance by identifying the flora that grow in 8 areas of the national park. Materials and Methods Overview on research sites Gyeongju National Park stretches 8 areas in and around Gyeongju-si, Gyeongsangbukdo. Tohansan area (76.95 km 2 ), Namsan area (21.0 km 2 ), and Daebon area were designated as national parks in 1968, covering a total of km 2. With the addition (1.0 km 2 ) to Daebon area in 1971, Seoak area (4.30 km 2 ), Hwarang area (3.90 km 2 ), Sogeumgangsan area (6.8 km 2 ), and Danseoksan area (14.0 km 2 ) were included into the national park, making it a total of km 2. Currently, the Gyeongju National Park covers km 2 with the new inclusion of Gumisan area (6.11 km 2 ) in Of the park, an area of km 2 is designated as national conservation area, km 2 as national environmental area, and km 2 as communities. Research Method The research into the flora and vegetation conducted three

On the other hand, Pte-Q was obtained to fathom the degree of damage to forest vegetation. Results and Consideration The Flora For the flora, Kim (1994) reported 81 families, 208 genuses, 238 species, 1 sub-species, 37 varieties and 1 forma which totalled 277 taxons while Lee (1997) reported 39 orders, 109 families, 332 genuses, 458 species, 1 subspecies, 71 varieties and 10 forma which totalled 540 taxons. This research found 39 orders, 112 families, 354 genuses, 515 species, 1 subspecies, 78 varieties and 11 forma which totalled 605 taxons. Table 2.

Lee (1997) reported Pte-Q, which is a barometer of damage to the forest vegetation, was 0.62, however, this research found Pte-Q was 1.35, which meant that the forest succession has progressed better than 10 years. It turned out higher than those of Mt. Gayasan (1.27), Mt. Juwangsan (0.95), and Mt. Chiaksan (0.89). In the Tohamsan area, Nymphea tetragona var. angusta, Iris pseudoacorus, Spirodela polyrhiza, Trapa japonica, Potamogeton crispus inhabited ponds in the front yard of Bulguksa Temple. The southern slope of Mt. Tohansan seemed to heavily be inhabited, but the dominant species was Pinus densiflora. P. koraiensis grew in some areas. Quercus mongolica was dominant in the area from the Iljumun Gate of Seokguram to the mountain top and Styrax japonica, Abies holophylla, Corylus heterophylla var. thunbergii, Rhododendron mucronulatum var. ciliatum, Prunus sargentii, Fraxinus rhynchophylla, Castanea creanta, and Tilia taquetii grew as well. Pinus koraiensis in stock on the southwestern slope while Q. variabilis and Q. mongolica lived in stock 300 to 600 m on the western, northern, and eastern slopes. Q. mongolica lived in stock near the Manhobong and Q. mongolica, Pinus densiflora, and Larix kaempferi lived in stock on the northwestern slope of Manhobong. Q. variabilis and Q. acutissima lived in stock in Sibugeo-ri on the northern slope of Mt. Tohamsan. Carpinus laxiflora lived in stock in the valley. Q. variabilis lived in stock on the Upoongi slope, Beomgok-ri and near Mt. Baikdosan, Janghang-ri, Yangbuk-myeon. Q. variabilis and Q. serrata lived in stock in the Hwangyongsaji valley, Hwangryong-dong. Q. variabilis and Q. acutissima lived in stock on the southern slope of Hantibeodeul. Some areas of the northern slope of Hwangryongsaji and Chamnamujeon were oxidation ponds, where Quercus species formed coppice forest. On the verge between Deok-

18 38 Sang-Myong Lee, Hwa-Yun Lee, Yu-Mi Lee, Soo-Hyun Park, Byoung-Chun Lee, and Won-Hyeon Lim dong and Eumgok-dong slopes grew Pinus densiflora. About 20 to 30 cm Platycarya strobilacea DBH grew in stock 300 meters high from Deok-dong to Mt. Cheongsan while acacia lived in stock around Deokdongho Lake. Q. variabilis and Q. mongolica lived in stock under 400 meters high. Q. serrata, Q. alinena, Zanthoxylum schinifolium, Prunus sargentii, Fagara mantschurica var. inermis, Pinus densiflora, Picrasma quassioides, Platycarya strobilacea, Styrax japonica, Cornus controversa, Alangium platanifolium var. macrophyllum, Zelkova serrata, Alangium platarfolim, and Morus bombycis grew under 400 m high. Q. mongolica lived in stock 400 m or higher and there were colonies of Q. variabilis and Q. alinena on the slope toward the look-out shed (Gyeongju Ranch). There were a colony of Q. variabilis and a colony of Q. mongolica and Q. serrata on the northern slope of Orion Ranch. There were relicts of Pinus densiflora, Carpinus laxiflora, and Zelkova serrata in the vicinity of the Girimsa Temple. Forests in the Daebon area, called Gampo area, were composed of colonies of Pinus thunbergii. There were a colony of Q. variabilis in the valleys, a colony of Phyllostachys nigra var. henonis near residential areas, and a colony of Robinia pseudo-acacia near cultivated land. Zostera marina prevailed on the beds of the sea and Phyllospadix iwatensis lived on subtidal rocky shore. Aster spathulifoliusm, Orostachys malacophyllus, Vitex rotundifolia, Sedum oryzifolium, and Youngia denticulata prevailed on the coastal cliffs. P. koraiensis was planted on some of the northwestern slope. In the Seoak area, a colony of P. densiflora prevailed and with human intervention, a colony of acacia were planted on the edge of the pine tree colony. Robinia pseudo-acacia was planted on the verge of eastern slope and northwestern slope of the Hwarang area. Colonies of P. densiflora were found on the northern slope. The southern slope was an oxidated land and showed the first stage succession where a sprout forest of oaks were developed. A colony of P. densiflora was dominant in the whole Sogeumgang area and a colony of P. thunbergii was formed in a shape of band on its verge, which was presumably planted. A colony of Q. acutissima was formed on some of the western slope of Yonggang-dong. There was a military base in the Dongcheon-dong valley, which may give damage to surrounding forests. Larix kaempferi was planted on the verge of the northwestern slope and a colony of P. densiflora grew on the verge of western slope and around 600 m high on the northwestern slope of Danseoksan area. Q. variabilis grew in stock on the southern slope, Q. serrata and Q. alinena prevailed in stock on the edge of northern slope, of the Sinseonsa Temple. Q. acutissima grew in stock around 600 m high south of the mountain top, and Q. mongolica lived in stock around the top. In addition, colonies of Q. serrata were formed mostly in mid-slopes. Colonies of P. densiflora prevailed mostly in the Gumisan area and P. thunbergii was dominant on the edge of Haguri. Colonies of Q. variabilis prevailed on the northeastern and northwestern slopes of Sanamsa-ri. Larix kaempferi was planted on some of the eastern slope of Mt. Gumisan and some of the back slope of Gajeong-ri. Colonies of P. thunbergii were formed in a shape of band on the western, northern and eastern slopes of the Namsan area. Except the colonies of Phyllostachys nigra var. henonis on some verge area near Hwarang Training Center, colonies of P. densiflora prevailed on most of the area. The whole Namsan area was covered with colonies of P. densiflora. On the other hand, aquatic plants such as lotus, Trapa japonica, Ceratophyllum demersum, Spirodela polyrhiza, Lemna perpusilla, Hydrilla verticillata, and Typha angustata lived in the pond beside Dongiljeon in Namsan-dong.
